Smaller Ignition Coils
The Vortec 6.0L’s individual coil-near-plug ignition features advanced coils developed for the LS2 and LS7 Corvette V8s. The new coils are smaller and lighter than those used on previous Vortec V8s, and while they are still mounted on the rocker covers, they attach with a new mounting bracket that simplifies engine assembly. An individual coil for each spark plug delivers maximum voltage and consistent spark density, with no variation between cylinders.

Iridium Tip Spark Plugs
Improvements to the Vortec 6.0L’s ignition system include advanced spark-plug technology. Its spark plugs have an iridium electrode tip and an iridium core in the conductor. The iridium plug has a recommended life of 100,000 miles, but it offers a number of advantages over the platinum-tip plugs previously used in the Vortec V8s.

The iridium spark plug has higher internal resistance, maintaining optimal spark density over its useful life. Its “self-cleaning” properties are improved, decreasing potential for plug fouling and further reducing the likelihood of maintenance over the 100,000-mile plug life. The electrode design improves combustion efficiency for maximum fuel economy and minimum emissions. Finally, iridium is more plentiful than platinum, reducing the plug’s material cost and preserving scarce noble metals.


Overview
The Vortec V8s have fueled GM’s leadership in truck sales because they provide the right technology for the job. Case in point: the Gen IV Vortec 6.0Ls.

The cast-iron block Vortec 6.0L (RPO LY6) was developed for heavy-duty applications, such as the all-new Chevy Silverado and GMC Sierra 2500 HDs. The LY6 has undergone the most rigorous lab- and road-testing process in small-block history. It’s validated to achieve 200,000 miles of operation in typical applications. The aluminum-block 6.0L was developed for maximum towing capability in vehicles like the Chevy Suburban. Its Active Fuel Management cylinder-deactivation technology improves fuel-economy when the trailer is empty or left behind.

The Gen IV Vortec 6.0Ls build on the solid foundation laid by their immediate predecessors: The Gen III Vortec V8s. Gen III introduced a host of advanced technologies to the overhead-valve V8, including aluminum cylinder heads, a thermoplastic intake manifold and electronic throttle control. Cylinder heads were designed with replicated ports that are identical in every detail, allowing constant cylinder-to-cylinder airflow. The valvetrain was developed on the belief that lighter is more efficient. A steel camshaft provides excellent durability. Steel roller rockers add stiffness, allowing greater engine speed with less vibration. Hydraulic roller lifters reduce friction for better fuel economy and wear resistance.

With their increase in output and fuel efficiency, the Gen IV small blocks share their predecessors’ low-maintenance requirements. The spark plugs extend anticipated plug life to 100,000 miles, while the coolant maintains its cooling and corrosion-inhibiting properties for 150,000 miles. Scheduled maintenance is limited to oil changes, and thanks to GM’s industry-leading Oil Life System, a customer should never pay for an unnecessary change. The Vortec 6.0L’s ECM records engine temperature, length of operation at a given temperature and several other operating parameters, and then indicates an oil change when it's actually needed, rather than according to a predetermined interval.

 

LOL , any more questions ?

 

holy crap thats a lot of info

 

thanks bro that was perfect

 

Anything else just click the powertrain link and it list all the current engines with info.

 

anybody know the comp. on these new set up?

 

Both the L76 and LY6 6.0L are 9.6:1 compression ratio



The L92 is 10.5:1

 

SO the l76 would love boost then Im guessing...

 

turbo sounds good with that comp.
